经调查,危害思茅松小蠹虫种类有3亚科11属15种,其中7种为思茅松(寄主)及分布新记录种。云南松梢小蠹、思茅四眼小蠹、额毛小蠹及云南切梢小蠹是思茅松的主要害虫,应列为该区域主要的检疫、监测和防治对象。研究结果表明,海拔高度、土壤综合肥力、采脂强度、坡向、林分结构是影响小蠹虫发生程度的关键因子。研究揭示了小蠹虫成灾的林分与不成灾林分的生态学特征,为营造抗小蠹虫林分提供了理论依据。
After investigation, the species of Sinophilia bark beetle have 3 subfamilies, 11 genera and 15 species, of which 7 species are Pinus kesiya (Host) and new recorded species. Pinus yunnanensis, Simao tinnitus, Pinnacle beetle and Pinus yunnanensis are the main pests of Pinus kesiya and should be listed as the main quarantine, monitoring and control objects in this area. The results showed that altitude, soil fertility, lipid fortification, aspect and stand structure were the key factors affecting the occurrence of bark beetles. The study revealed the ecological characteristics of the bark beetle-affected and unbroken stand, which provided a theoretical basis for the construction of anti-bark beetle stand.
